A 0.6V 70-dB SNDR energy efficient hearing aid current mode readout amplifier using accuracy compensation and adaptive bias current techniques

Abstract

An energy efficient hearing aid current mode readout amplifier using accuracy compensation and adaptive bias current techniques is presented, for the improved accuracy with the saved power. Compared with the conventional current mode amplifiers, the amplifier with the techniques is characterized by the pole-zero canceling feedback loop and the adaptive… (More)
